Will a bathroom vent fan work properly with this roof cap on a 9/12 pitch roof? In particular, does the large angle of the roof negatively impact the baffle and/or the air flow?
Asked by: Homeowner
Looking at the ones I bought the damper should work fine up to at least a 12/12 pitch. mouting angle will not affect the air flow.

If you remove the mesh and replace it with a mesh insert that would allow you to keep birds out, but let lent passes, can this work even though it says "not for dryer venting"?
Asked by: RPW
Just buy one designed for dryer venting, your dryer does not have enough pressure to blow and hold open the damper flap. That is the reason it says not for dryer venting.
